I didn't mention RDF/XML, I referred to RDF. As you can see, the letters
R-D-F are prone to confusion, all the time. And when it isn't confusion
you end up with gut-reaction style political reactions. This is the sad
nature of RDF, unfortunately.

You think you are speaking about a model, but you aren't. You are
speaking about RDF syntaxes. We have a directed graph model that holds
claims that can be matched to claims in an x.509 based security token
via the semantics of its relations. We can talk about WebID without
implementation details like the syntaxes for directed graph representation.
RDF is but one set of syntaxes for representing directed graphs. It just
isn't much more than that. RDFs and OWL semantics aren't inextricably
bound to RDF syntax either.

In our solution we don't do anything like that. We just use the
Fingerprint (hash of claims) as an option for determining the mirror of
the claims held in the x.509 based security token . The only issue with
the current incarnation of our solution is the fact that its based on us
writing drivers for the Facebook, Twitter, LinkedIn, and AtomPub
protocols. The next incarnation will simply build on that and produce
ProxyURIs, once in place others relying agents won't have to implement
their own drivers since follow-your-nose will just work since the URIs
will resolve to a navigable directed graph serialized in a variety for
graph representation formats (RDF and non RDF family).

Peter is seeking a way to place the mirror of his x.509 claims into a
WordPress post. The problem he has is that like most Web 2.0 solutions,
Wordpress is very restrictive, so he can't put (X)HTML+RDFa in there.

Of course not. But I am interested in pragmatic ways of publishing WebID
related claims to Blog posts. I know this is critical to mass adoption
of WebID.

Peter is seeking a pragmatic solution devoid of religion and politics.
